The deposit is one month. Then the agency asks for two more, a bank guarantee and a rent-default policy, and the total starts to look like a second mortgage. Some of that is normal in the Spanish market and some of it is a landlord testing how much you will accept. The gap between the two is mostly negotiation, so it pays to know which is which.
Spanish law separates them, and the separation matters when you negotiate.
An aval bancario is your bank promising the landlord to pay if you don't. The bank carries the risk, so it usually asks you to block a sum as collateral, often three to six months of rent, and it charges a fee. That fee runs around 0.5% to 2% of the guaranteed amount a year at most entities, and can reach 2% to 3% for higher-risk files. No law makes it compulsory, and for a standard residential lease a landlord cannot stack it on top of the legal cash caps.
Where it does become common is exactly where our clients rent: high-value villas in Barcelona, Alella, Sant Andreu de Llavaneres and the rest of the Maresme coast. On a €6,000-a-month house, an owner dealing with an expat tenant they have never met will sometimes prefer a bank guarantee to three months of cash.
A personal guarantee is lighter and costs nothing. A relative, an employer or a colleague signs to cover the rent if you default. Landlords accept it more readily when the guarantor has Spanish income or property, because enforcing a guarantee against someone abroad is more work than it sounds.
Rent-default insurance, seguro de impago de alquiler, is taken out by the owner and not the tenant. It costs the landlord roughly 3% to 5% of the annual rent. What matters for you is that the insurer sets the bar: a stable contract, payslips or tax returns, and a deposit already in place. A newly arrived expat with a foreign employer can fail that checklist even when the rent is obviously affordable.
The two-month limit belongs to residential leases under the LAU. Temporary and seasonal contracts sit outside it and guarantees there are freely negotiated. That is why a six-month corporate let in Maresme can ask for more up front than a five-year family lease. If you are signing a temporary contract, read the guarantee clause twice and ask what happens to it if you extend.
One last thing about getting it back. The deposit is returned at the end of the lease minus proven damage, and delays are common. Photograph everything at check-in, keep the signed inventory, and put the return terms in the contract. It is boring, and it works.
Still sorting out how you will actually pay the rent from abroad? That side is covered in renting in Spain without a Spanish bank account.
